Question:
Here I am agian.Cisco 3560V2 Price Please look at the following commands:
address-family ipv4 vrf B
network 10.0.0 .1
0.0.0.0
network 192.168.1.0 0.0.0 .255
no auto-summary
autonomous-system 220
exit address-family
What exactly does address-family mean? Can anyone put it in context so I can
understand it? And what is the
autonomous-system 220 doing there? You
may not believe how much seemingly trivia issues such as these can be great
sources of impediments to a learner trying to muscle in on the act.
Answer:
in the configuration example that you have
reported the address-family portion refers to running EIGRP for vrf A.
The autonomous system command makes the
router to send EIGRP packets with EIGRP AS= 220 on the interfaces associated to
vrf A, and to accept packets for EIGRP with AS=220 on the same interfaces of
vrf A. In this way the router can talk with a CE router that is running EIGRP
with AS=220.
The EIGRP AS number must match to form a
valid EIGRP adjacency, the autonoumous system command allows to Cisco 3560 use a different
AS to/from each VRF according to needs.
